The KML file MinFile_production_ts.kmz contains 1,696 past and current producing mines over the last 160 years in British Columbia that can be displayed at any range or point of time by using the Time Slider on Google Earth®. Only mines with known operating years are included in this KML file.

Regionated KML files have been created to provide a lightweight and quick display of over 12,500 mineral occurrences on Google Earth®. An application has been developed to extract the data from the MINFILE database and style the occurrences based on their status.

To speed up the display of over 60,000 Regional Geochemical Survey (RGS) sites on Google Earth®, regionated KML files have been produced. In this release, the data is extracted from the RGS database and the sample sites are ranked or scored based on copper content. Due to the large number of sample sites, a single KML file containing all the sites would be too big both for displaying on Google Earth® or as a network link from a website. The regionation technique allows the creation of thousands of inter-linked small KML files (file sizes 9 KB or less in this case), and only fetches and displays a small number of KML files at a given viewing altitude, which significantly improves the performance of loading and displaying the sample sites.

Poster Highlights in the BC Room

The BC Geological Survey, in conjunction with Mineral Titles, Ministry of Forests, Lands and Natural Resources and the Environmental Assessment Office will be providing informal presentations in the BC Room [Seymour Room]. The presentations will be made over the course of Round Up and the feature event of the BC Geological Survey will be late Tuesday afternoon. Topics covered will include geological highlights, Mineral Titles information and permitting / environmental assessment information. These are short presentations and will include opportunities for discussion and questions from clients to Ministry staff. A detailed schedule is available at the Province of BC corporate booth as well as in the BC Room.
